U2711 DVI issues

post #1 of 2
Thread Starter 
Hey all, I just got my U2711 in the mail and quickly hooked it up to my main PC. Unfortunately there was a lot of distortion/corruption, the display was working at 2560x1440 but the distortion was far too distracting. Tons of tiny blue pixels flickering on and off around the desktop. Focusing mainly on the darker areas, but not dependent on them. I tried all the configuration settings in the AMD CCC and on the monitor itself. I tried using a non-dual link dvi cable but the distortion was far worse, you need a dual link to support the high resolution. I tried reverting drivers, and the latest. I also tried my old 8800GT but that one wouldn't get anything on to the monitor, the BIOS could post to it but as soon as the OS was loaded nothing was output to the monitor.

I finally decided to try the display port and everything worked perfectly. I am wondering if there are some issues with my new monitor or if the issues are coming from the graphics card. (ati hd 5770).

Does anyone else have the Dell U2711 functioning perfectly over DVI with a 5770? (or 8800gt)
